What is up with Armstrong pumps. There website claims they are quite but all of the maintenance free pumps are anything but and leak within a month or two unless they are installed in a remote location where nobody would notice them leaking until the next maintenance cycle of the boiler. The rep here in town acts like they have no idea what’s going on like I’m the problem and they must think I’m stupid and have no friends because others are telling me there is a problem with Armstrong’s maintenance free pumps. Anybody else experiencing problems with them.

What are you having for lunch these days?

Excellent job. You were able to decipher the symptoms and it lead you to the issue. True pro.

Not to sound smug but it boggles my mind how they allow themselves to put on the market units with all the wiring unprotected and dangling around like that ... To us it just looks out of this world. Great find though 👍

Such a thorough and thoughtful video. Thank you for sharing all of your experience with us.

Good stuff, thanks! Not many guys working with TU on here, you ever see any Horizon units?

Bolt cutters are better

Does this bag come with a shoulder strap or do you have to purchase that separately?

Great info

There is one reason to not put on belts like that. Some of the new Carrier units have the pulley made out of plastic. Really. Looked like it was metal. I didn't know, until I cracked it using my screwdriver to get the new belt on. Aside from that, I've never had any issues with the 'wrong way'.

Nice job thanks for sharing

Outstanding

Get yourself a bearing heater and a heat crayon as to not overheat . They will drop right on

Great video man ! i need to master these units

I agree with your purging the nitrogen then shutting it off. I to had pin holes from having a constant purge going. Great video.

Nice. Innovative. Simple. Functional.

Fantastic!

unistrut, of course, this is so handy.

Great idea! This will definitely help make job easier!!

I love the DeWalt 90 degree drill extension for those spots

Very customed.. I like that

That thing is absolutely phenomenal Had one a couple years now and use it all the time

I use that thing all the time on ice machines

I do apartment maintenance and that ratchet has saved my ass many times.

Love beta tools had them for 30 years broken very little not cheap

Get a hex bit for it and now gas valve plugs are easy to pull. I love that little ratchet, got a couple. 😁

I’ll be buying this…

Whenever i need something dewalt doesnt have klein is the furst thing i go to if i was in hvac or electric i would get nothing but klein only ones who havent sold out yet

Yup, bought one 3 years ago & have gotten 2 more since. Damn handy. There's an Icon mini ratchet box set w/extension & 32bits from Harbor freight that pairs really well with this. The icon driver is nice and all, with a swivel, but much thicker w/a round handle that makes it a bit unwieldy in tight spaces. So I often use the Klein driver instead.

I’m sold

Oh fuuuuuck, now that i see the loop used like that im sold.

The torque spec is one finger tight 😂

Klein has been on point with the new stuff lately

I’ve seen these at the distributor I go to, I still have $400 on my Christmas tool bonus, might have to grab me one of these

You can push the bit in to get more clearance!

Yes dude! Commercial hvac tech here. I use mine all the time. Got me out of quite a few jams

Nice! I even use it with the longer malco adapter. Perfect length for an oil burner motor.

The smaller tools have been my favorite in commercial!

Love mine. Get you in places that you thought were impossible

That thing is a dawg. I take panel doors off with it 😂

Yep, love mine for those tight spots

Ooo. Love that design.

Question! Why is mine not doing any heating

Thanks! I like how you touched on different thickness sheaves. The adjustable ones are so common nowadays so it makes it more difficult to align and they rarely ever get swapped out. I swear bearings and belts are one of the least understood things in HVAC next to airflow lol.

If only I had this information 8 hours ago😂

The balance holes in the bottom pully are part of the problem.

I carry a roll of floss in my tool bag to use as a straight edge. Always have the right length as needed

Great job 👏🏻 I had to do something similar to this recently.. only been doing this 5 years and I don’t have a whole lot of experience doings pumps like this. It was a b**tch! You made it look easy. Ran into similar issues like the pipe weighing down on the bearing assembly causing it to kind of cock eye upward… aligning the coupling took some time to. Hopefully my next one will go smoother haha good job again man.

I replaced a set of bearings on an Addison OAU. I was unable to order parts direct from manufacturer (backordered), so I took some measurements and found what looked to be a suitable replacement online. When they arrived, I noticed they said 'Dodge' on them. I thought that was a little odd but I was confident in my measurements so proceeded. That pulley did NOT want to come off. It took a copious amount of sanding, lubricating, and strategic application of force before it made that 'ting' sound and slid off. When I finally got the old bearings off, I saw they, too, had Dodge stamped in them. I've seen those same Dodge bearings on other equipment since (the new Trane Odyssey Symbio systems, for one). I've been doing more commercial and light industrial lately, no help, no training, just learn as I go. Not so bad, if there's a puzzle I just let the office know this might take awhile. Most of the time, I can figure it out. On a few occasions I just sit in my van for an hour or so reading the manual. Sometimes, nothing makes any sense and then the light bulb comes on and all the puzzle pieces fit. I learn more on those jobs than the ones that go smoothly.

The "gen I" torque titans had ALOT of issues with rolling off the sheaves/pulleys even when put on the 'correct' way and to spec. Gen II came out pretty quick to avoid that I believe.
